Cl. 9013.6 Claims ABSTRACT OF THE DISCLOSURE An engraving machine is disclosed having interchangeable sets of jaw extensions which render the machine uni versal in that curved and flatware may be engraved using one set of jaw extensions. The jaw extensions are interchangeably attached to vise jaws. The vise jaws are mounted for up and down movement as well as rotary movement.

This invention is directed to a universal engraving machine which can handle flatware such as trays up to 22 inches wide as well as the tiniest anklet. Also, the machine is adapted to facilitate engraving round or curved objects such as ice buckets, trophy bowls, trophies, pitchers, etc. The articles to be engraved are supported by jaw extensions extending from vise jaws. Means are provided for rotating the vise jaws to any angular position as well as raising and lowering of the vise jaws.

It is an object of the present invention to provide a universal engraving machine which can facilitate engraving large flatware such as trays as well as curved ware such as bowls, trophy cups, ice buckets, etc.

It is another object of the present invention to provide an engraving machine having novel jaw extensions to facilitate rotating large curved ware such as bowls, trophy cups, ice buckets and the like up to 15 inches in diameter.

Other objects will appear hereinafter.

For the purpose of illustrating the invention, there is shown in the drawings a form which is presently preferred; it being understood, however, that this invention is not limited to the precise arrangements and instrumentalities shown.

FIG. 1 is a side elevation view of the engraving machine of the present invention;

FIG. 2 is a top plan view of the engraving machine of the present invention;

FIG. 3 is a partial perspective view of the vise structure;

FIG. 4 is a side elevation view of the vise structure on an enlarged scale;

FIG. 5 is a sectional view taken along the line 55 in FIG. 4; and

FIG. 6 is a side view taken along the line 66 in FIG. 4.

Referring to the drawings in detail, wherein like numerals indicate like elements, there is shown an engraving machine in accordance with the present invention designated generally as 10.

The engraving machine 10 includes a frame which includes a support member 12 on the left side of FIGS. 1 and 2 supported by legs 14. Member 12 is coupled to the legs 14 by C-shaped adapters 16. On the opposite side of the frame. there is provided a second support member 18.

Member 18 is supported by the legs 20 and coupled thereto by C-shaped adapters 22.

The legs 14 and 20 are interconnected with a hub 32 by means of webs 24, 26, 28 and 30.

The hub 32 supports a vertical shaft 31 for up, down and rotary movement. The upper end of shaft 31 is connected to a journal 33 which supports a way support 38. A jack 34 is connected to the journal 33. Jack 34 is provided with an actuating handle 36 and is connected to the webs 24 and 26 by means of brackets 35 and 37.

Ways 40 and 42 are connected to the support 38 for guiding vise jaws 44 and 46. A threaded shaft 48 is threadedly coupled to the jaws 44 and 46 to cause them to move toward and away from each other when handle 50 is rotated. The length of ways 40 and 42 as well as the shaft 48 is chosen in a manner so that they may rotate through 360 when disposed at an elevation corresponding to the elevation of the adapters 16 and 22. When below the plane of the adapters 16 and 22, the vise jaws may rotate through a limited angle of approximately 90. A set screw having a handle 53 is provided for locking the shaft 31 to the hub 32 in any chosen angular disposition for the vises 44 and 46.

A pattern plate 52 is removably supported on the member 18 and contains the printed matter to be engraved on the object.

A stylus 54 is adapted to follow the printed matter on plate 52. Stylus 54 is supported at one end of arm 56. The other end of arm 56 is pivotably coupled to one end of arm 60 by pin 58.

The other end of arm 60 is pivotably coupled to a carriage 64 by means of pin 62. Carriage 64 includes a rack 66 meshing with a pinion not shown. The pinion is rotatable by means of handle 68 to cause the carriage 64 to reciprocate toward and away from the support 18.

An arm 70 has one end pivotably interconnected to the arm 60 intermediate the ends thereof by means of pin 72. See FIG. 2. The other end of arm 70 is pivotably connected to one end of arm 74 by means of pin 76. The other end of arm 74 is pivotably connected to arm 56 intermediate its ends by pin 78. Hereinafter, the arms 56, 60, 70 and 74 which support the stylus 54 may be referred to as a pantograph. An engraving tool is supported by the pantograph and provided with a lever 82 which permits selective lowering of the engraving tool. Lever 82 is spring-biased upwardly. The engraving tool is supported by the arm 70.

In order that the jaws 44 and 46 may support a large fiat tray 84, the jaws are provided with jaw extensions. Vise 44 is provided with jaw extension 86. Vise 46 is provided with jaw extension 88. The jaw extensions 86 and 88 are identical. Hence, only jaw extension 86 will be described in detail with corresponding elements being provided with corresponding primed numerals.

The jaw extension 86 includes a plate 90 which is removably connected to the upper surface of the jaw 44 by means of screws 92. The plate 90 includes projections 94 and 96 in the form of blocks. The block 94 has a face 98 and block 96 has a face 100. The faces 98 and 100 lie in planes which converge in a direction away from vise 46 and are at an angle of approximately 75 with the horizontal. The faces 98 and 100 engage the tray 84 at spaced points adjacent one end of the tray.

In order to accommodate curved ware, the jaws 44 and 46 are provided with jaw extensions 102 and 102'. The extensions 102 and 102' are identical except as will be made clear hereinafter. Only jaw extension 192 is described in detail with corresponding primed numerals being provided for the extension 102'.

In order to accommodate the jaw extension 1112, the vise 44 is provided with a horizontally disposed bore 104 extending through a boss 108. A shaft 106 extends through the bore 104 and boss 108. The lefthand end of the shaft 106 is provided with a knob 11% and a reduced diameter portion adapted to abut the boss 108. The righthand end of shaft 106 is threaded.

The extension 102 includes a main portion 114 having a downwardly extending leg 112. The threaded righthand end of shaft 106 is threadedly coupled to the leg 112 with a shoulder 113 resting on the upper surface of the jaw 44. Thus, the extension 102 is in intimate contact with the jaw 44 in vertical and horizontal directions. Adjustment of the knob 110 causes the leg 112 to firmly engage the vertical surface of the jaw 44.

A cone 116 is rotatably supported at the upper end of body portion 114. A cup 118 is rotatably supported by shaft 120 at the upper end of jaw extension body portion 114'. The cones 116 and 118 are interchangeable and made from a flexible resilient material such as rubber capable of having good frictional contact with the work piece. The cone 116 and cup 118 would be utilized when engraving a large trophy cup. Cone 116 would engage the bottom conical surface on the base of the trophy cup while cup 118 would enter the open mouth at the top of the trophy cup.

The shaft 122 on which the cone 116 is supported is connected at its lefthand end in FIG. 4 to a gear 124. Gear 124 is in meshing engagement with gear 126 on horizontally disposed shaft 128. Shaft 128 is rotatably supported at its ends by the body portion 114 and provided with an actuating handle 130. Rotation of handle 130 will rotate the cone 116 and thereby cause the trophy cup or other curved object to rotate about the axis of shafts 120 and 122.

In view of the above, it is believed that the operation of the engraving machine will be readily apparent to those skilled in the art. When engraving curved ware such as ice buckets, bowls, trophy cups, and the like, the jaw extensions 114 and 114 will be utilized to support the ends of the curved object. Rotation of the object during engraving may be attained by manually rotating handle 130.

When it is desired to engrave large flatware such as a tray, jaw extensions 86 and 88 will be removably con nected to the vise jaws 44 and 46. When small items such as watches or jewelry are to be engraved, the vise jaws 44 and 46 may be provided with jaw extensions positioned to extend toward each other. In each case, the jaw extensions embrace opposite sides or ends of the object being engraved without being physically connected to the object. In each case, the jaws 44 and 46 and their extensions may be moved upwardly or downwardly by actuating jack handle 36 and may be rotated about the axis of shaft 31 by loosening the set screw handle 53 and manually rotating the jaws to the desired angular position.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof.
